Proof step 26 from proof validref-ac (previous step)

∀ str, r, ty, class, st. validref(str, r, ty, addclass(class, fis0, st)) ↔ validref(str, r, ty, st) ⊦ fs .class = class, validref(str, r, ty, addclass(class, fis0, st)) ↔ validref(str, r, ty, st)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 25:
fs = mkfs(class0, ty0, fieldvar), ∀ str, r, ty, class, st. validref(str, r, ty, addclass(class, fis0, st)) ↔ validref(str, r, ty, st) ⊦ class0 = class, validref(str, r, ty, addclass(class, fis0, st)) ↔ validref(str, r, ty, st)

Rule argument
